One thing to keep an eye out for future episodes is this. For the bulk of the imps, genetically male imps have thick white stripes on their horns and white hair. Genetically female imps have thin white stripes on their horns and black hair. There are some imp races that go against that trend, such as the succubi and incubi. There are transgender imps, who do nothing with their horns, but do dye their hair to match the gender they identify as.
